+Subject: tests: fix use of uninitialized variable cpu_info
+
+On cpu-volume-test, cpu_info is initialized only on i386/amd64 systems,
+and otherwise passed on to pa_cpu_init_orc() uninitialized.
+
+If one was unlucky enough, they could end up with cpu_info.cpu_type ==
+PA_CPU_X86 on a non-x86 system, and use and test the Orc codepath
+without that being functional, and thus with the test failing.
+
+This has been observed in the wild on the ppc64el Debian buildds. See
+Debian bug #982740 for more context.
+
+Define cpu_info here in the same way as in other tests.
